Abstract
Cylinder for rubber mixing mill, consisting of a hollow cylinder 1 and two flange-journals 2, 3 and driven by a hydraulic motor 21 with a hollow shaft. The hollow cylinder has longitudinal channels 4 provided with solid rods 8 fastened in the two flanges. The temperature regulation of the cylinder is provided by a crossed dual circuit. The temperature regulating fluid circulates in longitudinal channels 4 then cools the inner wall 19 of the hollow cylinder before being evacuated along the axis of the cylinder.
Claims10
A cylinder for a mixing mill, comprising:
- a cylinder part having a plurality of longitudinal channels extending therethrough in substantially the axial direction of the cylinder part, said channels being substantially evenly distributed adjacent the external periphery of the cylinder part;
- solid rods extending through at least some of said channels to form annular passages therebetween;
- means for flowing heat exchanging liquid through said channels so as to form a cylinder temperature regulating circuit, and
- flange journals mounted to opposite axial ends of said cylinder part, said rods having ends passing through said flange journals, further including means for securing said rods to said flange journals such that said flange journals are secured to said cylinder part via said rods.
